We present the SHPRITZ Freerace Fin by Future Fly x Wind Lounge.
The SHPRITZ fin from Future Fly x Wind Lounge has a clear mission: to take your freerace experience to the next level by making it easier to rail your board and making your jibes smoother.
Technical Features
Of course, the fin’s characteristics are the result of years of development. The fin was designed by Future Fly in collaboration with Z-Fins. The profile of the renowned World Cup Fins was softened to allow for a more passive takeoff from the board and easier jibes. To achieve this, the fin was rounded toward the tip while maintaining a super-fast profile. The fin’s flex begins closer to the base and decreases toward the tip. The softer base provides a comfortable, balanced lift. Unlike slalom fins, the lift engages even without pressing hard against the fin, though it is not as strong. The fin was manufactured using a mold from high-quality carbon—both the fin and the fin head are made of carbon.
Size Recommendation
Since every setup is different, there are no definitive size recommendations. It’s best to ask the Wind Lounge team. To do so, please send a brief email (to willkommen@windlounge.de) specifying your height, weight, board, volume, width, and the sails you typically use. If you have specific issues, such as spin-outs, please mention them briefly as well. Otherwise, the Shpritz Fins follow the same sizing guidelines as other Fins.
Behind-the-Scenes Story
The fin was “discovered” as part of the White Tiger Program on Rhodes. There, Arnon Dagan and Mario Kümpel tested the fin, which was initially rather unremarkable. Compared to high-end slalom Fins, it didn’t offer the same top speed, but it came close. What stood out in particular was how easily the board could be edged and the smooth riding feel that was still maintained. While slalom fins required muscle power and technique to control, the riding experience with the Shpritz fin was significantly more relaxed. The same was observed during power jibes, which were easier to execute than with pure slalom fins. As a result, the fin became part of the White Tiger Program and is now in mass production.
